The raid setup is actually pretty flexible:

• 1 Main Tank - Demonology Warlock
• 1 Whelp/Elemental Tank - Protection Paladin/Warrior preferably
• 1 Drake Tank - Any tank should do
• 1 Main Tank Healer - Priest or Paladin
• 2 Drake tank/whelp tank/raid-healers - Any healing combo that has enough AoE healing for Twilight Torment. Succesful setups for us have been druid/druid, shaman/druid, paladin/druid.
• 3 DPS - A rogue is nice for enrage dispel, casters and dot classes are preferable but melee seems to work aswell.
• Replenishment dude - Hunters bring misdirection which can be nice, but isn't needed. Shadowpriests bring Vampiric Embrace and 3% hit for the raid. A paladin could be nice for putting up Judgement of Light when Twilight Torment is up, if you don't have a Holy Paladin for that.

That is, 2 tanks, 3 healers and 5 DPS, one of the DPS being a Demonology Warlock.

• Place Voidwalker at tank spot where it can avoid Flame Tsunami. See red cross.
  
• A tank pulls Sartharion in a straight line to the edge of the island, then Tricks of the Trade and Misdirection is used to direct Sartharion to the Voidwalker. 0 DPS on Sartharion.
• Everyone moves towards the other side of the island where Tenebron will land and await him.
• Tank picks Tenebron up and moves him to where Vesperon is going to land later on (right side of the island). This makes it easier for the MT healer to avoid walls, not having to worry about drake breaths.
• Bloodlust is used on Tenebron and he is killed preferably before second set of whelp spawns.
• Likely before Tenebron dies Shadron will land on the left side of the island. Misdirection is used to move him to the tank. Pray to avoid raid breaths!
• When Tenebron dies the raid finishes off the whelps and elementals with some AoE.
• If AoE is done before Vesperon lands some DPS can be made on Shadron before waiting, once Vesperon lands we switch to him. We kill Vesperon before Shadron!
• When Twilight Torment goes up we keep DPSing, with caution. Avoid Lava Strikes if possible and slowly burn down Vesperon. On our last kill Vesperon was up for 2 min 6 sec. We ignore the Acolytes for now.
• Once Vesperon is down all DPS except the Demo Warlock enters the portal, along with one of the healers. Acolyte of Vesperon is killed while Acolyte of Shadron is ignored. We leave Acolyte of Shadron alive not to have to kill it several times.
• Given that voidwalker healing is going okay we have gotten past the hardest part of the fight. The health penalty is removed and Twilight Torment is out of the picture. The raid and drake tank should be taking a lot less damage, giving the healers a bit more time to focus the voidwalker. Burn down Shadron.
• Once Shadron is dead the drake tank taunts Sartharion. AoE down elementals to clear up the add tank. Once this is done the whelp tank and all DPS (may include the demo warlock once Sartharion is taunted) go in and kill the Acolyte of Shadron, bringing one of the healers once again. During this time the MT will have to taunt the elementals that spawn unless the Demo Lock stays behind with his VW.
• Get Sartharion to 10% and then burn him down as quick as possible.
• Profit.

Doesn't really require bloodlust. It's entirely possible to get Tenebron down before the second whelp spawn without bloodlust, even though it doesn't hurt. If you happen to get a second whelp spawn it is manageable.

Misdirection isn't needed either, the tank can grab Shadron with ranged taunt paired with Avenger's Shield/Heroic Throw.
